Reuters. DaimlerChrysler’s first hydrogen-powered car using fuel cell technology will be on sale from 2012, according to a company executive.

“It (commercialization) will start in 2012,” Herbert Kohler, Vice President of the Body and Powertrain research unit at DaimlerChrysler told reporters in Brussels, on the margins of a hydrogen car technology exhibition.

But there are still technical obstacles to overcome such as extending fuel cells’ reliability and durability; ensuring that they start at sub-freezing temperatures; reducing costs, and storing enough hydrogen in a small enough space to be workable.
